Exactly why the worn out cliche still works around the world. 'Politics makes strange bedfellows'.
Hopefully this is all that is of import from this phrase. Since pre-world wars inter-country relations were no doubt worst compared to today. Yeah, now the past appears to be dredged up with the Ukraine land grab war, think of that as an opportunity to figure a way out of doing any business with the ruskies until they just fold, hopefully for good.
Not nice but neither is any war.
